In this study, soybean protein isolate (SPI) / bacterial cellulose (BC) co-assemblies replicate the fibrous network structure in animal fat to stabilize the 3D-printed high internal phase Pickering emulsion (HIPPE) gels with excellent processing characteristics. The SPI/BC co-assemblies, structured through pH shifting treatment, displayed exceptional emulsification and gelation properties. The relevant results indicate that the SPI/BC co-assemblies possess numerous hydrophobic and thiol groups on their surfaces.

Lipid oxidation hinders the development of water-in-oil (W/O) emulsions. This work aimed to determine the impact of soybean phosphatidylethanolamine (SP)/tamarind gum (TG) ratios on interface activity and anti-oxidant capacity of Maillard conjugates (MCs) in W/O emulsions. Results showed that grafting degree of MCs reached maximum with SP/TG ratio at 1:1 (43.

Monomer insertion, leading to the formation of an activated monomer complex, is a critical step in cationic ring-opening polymerization (CROP) of cyclic monomers, such as ε-caprolactone (CL). In this study, Density Functional Theory (DFT) calculations were employed to investigate the structural and electronic properties of four activated complexes at two Zr:B ratios (1:2 and 1:1), where Zr is the cationic zirconocene catalyst, Cp₂ZrMe⁺, and B is the borate cocatalyst, [MeB(CF)] or [B(CF)]. Steric hindrance at the reactive site was analyzed using topographic steric maps, while inter- and intramolecular interactions of the complex systems were examined through the Quantum Theory of Atoms in Molecules (QTAIM) and non-covalent interaction (NCI) analyses.

The lipophilicity of thirteen tacrine/piperidine-4-carboxamide derivatives was assessed using reversed-phase thin-layer chromatography (RP-TLC) with MeOH and acetonitrile (ACN) as organic modifiers. Among the parameters evaluated, the R and C values obtained using MeOH were identified as the most reliable for characterizing the lipophilicity of the investigated compounds. The observed differences in lipophilicity among the derivatives resulted from a delicate interplay of substituent effects (hydrophobicity, polarity, steric hindrance, and electronic effects), positional influence, and characteristics of the organic modifier.
